This is a pair of optional PSM Aluminum MBX7R EV2 Hex Drives in Standard offset. These hexes are made from 6012-T6 aluminum alloy material and feature milled pockets to remove as much unnecessary material as possible, without sacrificing strength and durability.

These standard hexes are the same size as the standard Mugen hex hubs (MUGE0239) and are compatible with any Mugen 1/8 vehicle that uses MUGE0239.
